DEVICE FOR FEEDING FIBER TO FIBER-TREATING MACHINES.

SPECIFICATION forming part of Letters Patent No. 545,189, datedAugust 27, 1895.

Application filed March 12, 1894- Serial No. 503,314. (No model.)

To (455 whom it may concern:

Be it known that 1, JAMES M. BLAISDELL, of Mays Landing, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvemen'tsin Devices for Feeding Fiber to Fiber Treating Machines, of which the following is a specification.

This invention has relation to machines for treating card and picker waste and other substances in which something more than the gravity of the material is necessary or desirable in order to feed the same into the machine or to the devices which operate thereon.

It is the object of the invention to provide means whereby card and picker waste and other stock or material may be automatically forced through the feeding-aperture of a cleaner or other machine, so that the operating devices may take hold thereof.

To these ends the invention consists of a fiber-treating or other machine provided with a feeding-aperture in combination with movable devices in proximity to the said aperture, constructed and operating to take the material and force it through the feeding-aperture, so that it will be engaged in desired quantity by the means designed to operate thereon.

Reference is to be had to the annexed drawings, and to the letters and figures marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

In the drawings, Figure l is a front elevation, parts being represented as in section, of a form of means embodying the invention. Fig. 2 is a side view of the same. Fig. 3 is a side elevation of the invention shown as used in connection with a picker and cleaner and a feedingmachine for supplying stock in substantially regular quantity to the invention to be acted upon thereby.

In the drawings, a designates what may be understood to be a machine for cleaning or extracting threads from waste fiber made on pickers, carding-machines, spinning frames and mules, the. b designates thefeeding-aperture formed in the bonnet or casing of the machine, through which the stock is supplied to the boaters or other devices adapted to act thereon. In the use of these machines it has heretofore been necessary for an attendant. to feed them by hand, crowding the material through the feed-aperture, so as that the beaters could take and act upon it. By my invention means are provided whereby this work is accomplished automatically, said means heiug capable of varying forms of construction and arrangement,that herein shown, by way of illustration, consisting of one or more plungers c, which rise above the material, and in descending crowd it through the aperture Z).

The plunger may be variously operated. As shown in the drawings, where two plungers are employed, they are constructed and arranged sovthat one shall descend while the other is rising. In this way the rising of one plunger is prevented from dragging material back or up with it by the descent of the other. To better enable the plungers to carry the stock toward the feeding-aperture they may be provided at their lower ends with downwardly and outwardly projecting spurs d, which as the plungers go down engage and carry the material down with them, and when they rise are released from the stock.

Of the various suitable means which may be employed for supporting, guiding, and reciprocating the plungers, that shown in the drawings is efficient for the purpose, in which 6 e designate cranks forming part of a shaft f, driven bya belt and pulleys. gg designate links or pitmen pivotally connected at their upper ends with the said cranks, and connect ed in like manner at their lower ends with the upper ends of the said plungers. The latter are guided by a bearing formed in a bracket h, attached to the hopper t, which is constructed to receive the stock to be acted upon and conduct it to the feeding-aperture b. The shaft f may also have certain of its bearings supported by the hopper.

In Fig. 3 I have shown the invention as connected with a fiber-feeding machine, so that stock may be supplied to the said invention automatically in regular quantity.

In the last-mentioned figure, j designates the box or hopper, is the supply-apron, Z is the spike or lifting apron, m is the stripper or evener, and u is the doffer, These parts may be of the form shown or any other suited for the purpose.

When an automatic feeder is employed in connection with the invention, the hopper vi will be constructed so that it may receive the stock from the said feeder and conduct it to the feeding-aperture Z7; and inasmuch as it may be desirable to move or swing the hopper out of the Way, so as to be able to raise the bonnet of the machine ct, I hinge the said hopper to the box or hopper j, as indicated at o, and secure it atother points by suitable latching means-as, for example, a staple p and hasp or hook g. The said hopper 2' is provided with converging walls at i t", and a reduced aperture 2 through which the plungers reciprocate. By providing the hopper with the converging walls the material is guided and crowdedinto the path of the plunger, so that it is easily forced into the fiber-treating" machine.

By the means described it is made unnecessary to employ a special attendant to feed a waste picker or cleaner, thread-extractor, or other similar machine, as has heretofore been the case, and the material may be applied to the machine more nearly constantly and evenly than by hand.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth allgt the forms in which it may be made or all of the modes of its use, it is declared thatwhat is claimed is- 3. A fiber-treating machine provided'with a hopper having converging walls and a reduced aperture at the delivering end,in combination with two oppositely reciprocating plungers moving rectilineally through said reduced aperture, and means for simultaneously operatingsaid plungers substantially as set forth.

2. A fiber treating machine provided with a feed aperture, and a hopper having converging walls and a reduced delivering aperture, in combination with two oppositely reciprocating plungers, moving rectilineally through said reduced aperture, guides for said plungers, and means for operating them simultaneously, substantially as set forth.

3. A fiber treating machine provided with a feed aperture, and-a hopper having a reduced delivering aperture, in combination with two oppositely reciprocating plungers lying side by side and moving rectilineally through said reduced aperture, guides for said plungers, a rotating crank-shaft, and links for connecting said plunger with the said .crank shaft, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 8d day of February, A. D. 1894.
